Title: Liq. sun shield for space between panes of window - comprising one or two liquid(s) with upper liq. coloured, and pref. circulated and heated in cold weather
Inventor: AGOT ERIC JOEL DIPL ING
IPC: G02B5/24
Filed: 1991-03-13
Abstract: The liquid sun shield, for windows composed of two glass panes, has the inner zone (1a) between the panes in the window (1) filled with one or two fluids (2a,2b). The upper fluid (2a) is darker than the lower fluid (2b), to reduce the intensity of sunlight passing through to the interior. In winter with ambient temps. of +50 deg. C and less, the fluid is heated automatically. The space (1a) between the window (1) panes is in a vacuum when the fluid is pumped back to its container. The fluids (2a,2b) leave no colour tracks within the space (1a) between the glass panes. The lower fluid (2b) is watery and transparent, while the upper fluid (2a) is oily and coloured. The fluids (2a,2b) are moved by an electro-motor (17) and two double-action pumps (12a,12b). The volume flows are set so that the dividing layer (19) between the fluids (2a,2b) can move up and down, and the upper fluid (2a) screens the sunlight, while a view can be obtained through the lower fluid (2b). The amount of dark and clear window areas is set by a push button. USE/ADVANTAGE - The sun shield is for the windows of vehicles, public service vehicles, caravans, boats, aircraft and buildings. The fluids can be structured according to the amount of sunlight to be screened, and they can also be used to defrost the windows.

Title: Prodn. of max. colour and aroma in prepn. of malt prod. - by injecting acid, base or electrolyte soln. to control pH during extrusion of cereal grains
Inventor: KROH LOTHAR DR SC NAT
IPC: A23L7/20
Filed: 1991-04-19
Abstract: Prepn. of a malty prod. from cereal grains for beer prodn.; or for addn. to bread and baked goods, where the cereal is extruded in a single- or double-screw extruder under heat and pressure, formation of a max. amt. of colour and aroma substances is attained by controlling the pH of the continuously prepd.  extrudate by injection of an acid, a base or an electrolyte soln.. Injection is pref. through the wall of the extruder, in a region where comminuted grains are present. The pH is brought to 5-9, and depends on the degree of browning of the extrudate or on the amt. or concn. of CO2 leaving the extruder and determined quantitatively. The acid is pref. lactic, acetic or ascorbic acid, HCl or H2SO4, the base pref. is NaOH, Mg(OH)2 or NH4oH, and the electrolyte soln. contains (NH4)2CO3 or Ca phosphate. The degree of browning of the extrudate is scanned by measuring reflected light. The pH of the extrudate is scanned continuously by a sensor in the extrudate and the injected amt. of acid, base or electrolyte is controlled, corresp. to the value given by the sensor, by a computer, so as to maintain the desired degree of browning of the extrudate. ADVANTAGE - Formation of colour and aroma is increased and is more uniform.

Patent DE-4117897-A1 (DE)
Inventor: OTTERBEIN STEFAN DR
IPC: B60G17/018
Filed: 1991-05-31
Abstract: The object of the system of the invention is the ''modal'' variant of sky-hook damping. The essential advantage of this variant over the local version is that the natural vibration forms can be individually damped. In addition, a defined rolling movement distribution can be set. To this end signals are found which represent the local bodyshell movements of the vehicle at selected points. Conclusions on the rising, rolling and pitching movements can be reached from these signals. These movements are given different weightings depending on the driving manoeuvres. Certain components of the bodyshell movement can be deliberately affected by controlling the damping system dependently upon the weighted rising, rolling and pitching movements.

Title: Procedure for filling container to prevent increase in gaseous volume - involves first filling container with gas which is saturated with liquid.
Inventor: CURTIUS FRITZ
IPC: B67D7/04
Filed: 1991-10-01
Abstract: In the first step the container (1) is filled with the required liquid in order to displace the volume of gas already in the container. In the second step the liquid is removed from the container and the inflowing gas flows over the surface of the specified liquid or over a surface wetted by the liquid. The container is thus filled with a gas which is saturated with the liquid vapour so that when the container is refilled with liquid no further vapour can be absorbed and consequently there is no increase in the  gaseous volume. USE/ADVANTAGE - Filling a container with a defined volume of petrol which is not subject to volumetric change.

Inventor: PERSSON DAN
IPC: H01R35/02
Filed: 1992-05-15
Abstract: A steering column assembly on a road vehicle has a facility to transmit signals between the moving wheel and the column in order that signals may be transmitted for air-bag operation.

Patent DE-4232932-A1 (DE)
Inventor: KASTNER HELMUT
IPC: A63G9/08
Filed: 1992-10-01
Abstract: Fairground rides (10) are known in which the passenger carrier (17) is assigned to the end of an extension arm (14) which can be moved about a horizontal axis of rotation (13). The movement of the passenger carrier substantially corresponds to that of the circular path of the extension, so that only very limited impressions of movement can be given. Provision is made according to the invention for the passenger carrier (17) to be capable of movement on at least one further circular path in the region of the end of the extension arm (14). The passengers are then moved on a cycloidal path. <IMAGE>

Title: Pneumo-hydraulic cylinder assembly - has transparent container from which oil is drawn into space behind working piston during forward working stroke and returned to container on reverse stroke
Inventor: MENKHOFF KARLHEINZ
IPC: F15B3/00
Filed: 1992-10-10
Abstract: The working piston (5) is extended by admitting air to inlet, when oil (2) is sucked into space behind the piston from the transparent container. As the working piston touches the workpiece, air is shut off to inlet (1) and admitted instead to inlet (6). The piston rod (7) of the air piston now advances into the oil space (4) behind the working piston and builds up the amplified working pressure. To reverse the working piston air is admitted to inlet (8), when the oil returns to the transparent container (3). USE/ADVANTAGE - Condition of oil is clearly visible. Several cylinders can be connected to one transparent oil tank.
